The lower portion of the rear portion 76 is adhered to the inner surface of the first rear wall 12.

In the first prototype sheet 3 and the second prototype sheet 4 configured in this manner, the respective indentations are folded in the same direction, and the adhesive is applied to the first bonding surface 38, respectively, and adhered to the corresponding surface. Thereby, the first prototype piece 3 forms the outer body 9 having the storage body 5 and the lid body 6, and the second prototype piece 4 forms the inner body 10, respectively. Next, the packaging container 1 is assembled by bonding the inner body 10 to the corresponding position of the outer body 9. In addition, the detailed description about the adhesion of the outer body 9 and the inner body 10 of the packaging container 1 is abbreviate|omitted here.

The packaging container 1 formed in this manner is such that when the packaging container 1 is formed from the prototype sheet 2, the tobacco bundle packaged inside the inner package is placed inside, thereby packaging the tobacco T. The packaging container 1 in which the tobacco bundle is packaged is such that the periphery of the packaging container 1 is enveloped by an outer film such as a transparent film. In this way, it becomes a tobacco product.

Next, the unsealing of the packaging container 1 configured in this manner and the opening and closing of the lid body 6 will be described. First, the outer packaging film is unsealed and the outer packaging film is unsealed and removed. After the outer film is removed, the lid body 6 is moved in a direction away from the storage body 5. By the movement of the lid body 6, the hinge portion 7 is bent, and the lid body 6 can be rotated about the hinge portion 7.

When the lid body 6 is rotated about the hinge portion 7, the projection portion 26 provided on the second rear wall 22 of the lid body 6 is also rotated about the hinge portion 7. At this time, the protruding portion 26 and the second rear wall 22 protrude in the opposite direction across the hinge portion 7, so that when the cover is made When the sixth portion is rotated in the opening direction as shown in Fig. 2, the protruding portion 26 moves toward the inner side of the storage body 5.
